SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 350,460, dated October1886 Application filed August 9, 1886. Serial No; 210,443. (No model.)

To all whom it may concern.-

Be it known that I, JAMES .GALBREATH LESLIE, of Oregon, in the county ofOgle and State of Illinois, have invented a new and Improved Sash-Lock,of which the following is a full, clear, and exact description. 3

My invention relates to the construction of a cheap, durable, andefficient sash lock which may be applied in connection with a sash thathas already been mounted, the ob ject of the invention being to providea lock whereby the sash may be held in any desired position, and whereinthe parts are so arranged that the sash may be removed from the case,

should such removal become necessary or desirable. V v

The invention consists in the peculiar construction and arrangement ofparts, as hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in both views.

Figure l is a face view of a portion of a sash of a window-frame, thesame being represented as provided with my improved form of sash-lock,parts being shown in section and Fig. *2 is a cross-sectional view takenon the line x w of Fig. 1.

In the drawings, 10 represents the window-casing, and 11 the upper sash.To the side face of the window-casing there is se cured a bracket, '12,in which two arms, 13, are mounted, said arms beingformed with apertures2, and being normally held apart by the action of a spring, 14, the endsof which spring ride in recesses 3, formed in the arms 13. A rod, 15,upon the upper end of which there is a catch or shoulder, 16, is, passedthrough the apertures 2 of the arms 13, the arrangement being such thatthe spring 14 will force the jaws apart, so that the edges of theinclined defining-walls of the apertures 2 will bind against the rod andhold it in position, preventing any longitudinal movement of the rod.

To the face of the sash 11 there is secured a second bracket, 17, saidbracket being formed with lugs or ears 18 between which lugs there ismounted a locking-dog, 19; This dog 19 consists, essentially, of acatch-tooth, 20, and a thumb-piece, 21, a spiral spring, 22, beingarranged between the thumb-piece and the bracket 17, in position so thatthe catch-tooth is normally held against the bracket 17. The bracket 17is formed with two upwa dly-eX- tending side walls, 23, between whicwalls the catch-tooth 20 enters, as clearly shown in Fig. 1.

In operation the upper end of the rod 15 is inserted between the walls23 of the bracket 17 and forced upward to a position so that theshoulder 16 is engaged by the catch-tooth 20 of the dog 19, the spring22 at this time acting to hold the catch-tooth in engagement with theshoulder. I

When the parts have been adjusted, as described, the sash may be movedto the required position by grasping the extending ends 'of the arms 13and compressing them against the tension of the spring 14, so as topermit the rod 15 to slide freely within the apertures 2 of said arms13. After the sash has been so moved, the pressure applied to the arms13 is relaxed, whereupon the springs 14 will act to separate the armsand cause the edges of the inclined walls of the slots 2 to bind againstthe rod and hold it in position against any attempted movement of thesash. WVhen it is desired to remove the sash from the window-casing, thethumb-piece 21 of the locking-dog 19 is forced inward against the actionof the spring 22, thus forcing the catchtooth 20out of engagement withthe shoulder 16, and the parts being so disconnected,

it will be seen that the sash may be removed from the casing in theordinary manner.

I am aware that sash-locks consisting of pivoted and spring-pressed dogshaving apertures in their ends and rods passingthrough the apertures ofthe said dogsis old, and I there fore do not claim such invention.

Having thus described my invent-ion, what I claim as new, and desire tosecure by Letters Patent, is

1. A sash lock consisting, essentially, of pivotally-mounted arms formedwith apertures 2, a spring, 14, arranged between the arms, a rod, 15,formed with a shoulder, 16,

and a bracket carryingMocking-dog, 19, snbmounted locking-dog, and aspring, 22, substantially as shown and described.

2. In' a sash lock, the combination, with a bracket, 12, ofpivotally-mounted arms 13, 5 formed with apertures 2, aspring, 14,arranged between the arms 13, a rod, 15, formed with a shoulder, 16, abracket, 17, a pivotally stantially as described.
